JUSTIFICATION AND APPROVAL

FOR OTHER THAN FULL AND OPEN COMPETITION

Under FAR 6.103-1 (DFARS CD 2026-O0017)

1. Contracting Activity:

The Contracting Agency responsible for this action is the U.S. Army Corps of Engineers – Baltimore District, Large Contracts, Environmental Architect/Engineer Team.

2. Description of Action:

The U.S. Army Corps of Engineers, Baltimore District (USACE-CENAB) requests exception for other than full and open competition and to extend the period of performance (POP) from 27 August 2026 to 11 July 2029 onContractW912DR18D0003, Task Order W912DR21F0329 for architect-engineering environmental services to complete certain tasks included in the original task order as described below. As part of the POP extension a contract modification will be required to account for the additional level of effort associated with the POP extension.

3. Description of Supplies/Services:

The contractor will complete certain architect-engineer environmental services in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) at the Former Nansemond Ordnance Depot (FNOD) in Suffolk, Virginia. Specifically, the contractor will complete: (1) the field scale treatability study, proposed plan (PP), and decision document (DD) at the TNT Area designated as Source Area 1 (SA-1), (2) underway tasks including AOC-13 feasibility study, and AOC-4 PP and DD.

4. Authority Cited:

This action is executed under 10 U.S.C. § 3204(a)(1), as implemented by FAR 6.103-1 (DFARS CD 2026-O0017) “Only one responsible source and no other supplies or services will satisfy agency requirements,” which permits the agency to execute this modification without full and open competition as the services required are available from only one responsible source and no other supplies or services will satisfy the requirement. Supplies and services may be deemed as available from only one source under this authority when awarding a contract for the continued provision of highly specialized services, would result in: “(i) Substantial duplication of cost to the Government that is not expected to be recovered through competition; or (ii) Unacceptable delays in fulfilling the agency’s requirements.” FAR 6.103-1(c)(2) (DFARS CD 2026-O0017).

5. Reason for Authority Cited:

Background:

Leidos, Inc. (“Leidos”) has been actively supporting environmental remediation and investigation efforts at FNOD under task order W912DR21F0329 since the task order was awarded in August 2021. The scope of the original task order W912DR21F0329 required the contractor to conduct a field scale treatability study, PP, and DD at SA-1, PP, DD for AOC-4, AOC-13 and NRB for the five-year POP.

Under their previous and ongoing efforts under the existing task order, Leidos has already developed and drafted the comprehensive Work Plan for this specific Treatability Study, which has been formally reviewed and approved by both the USACE Environmental and Munitions Center of Expertise (USACE-CX) and the Environmental Protection Agency (EPA).

Furthermore, Leidos has already mobilized and successfully conducted the first two baseline groundwater sampling events for this study. Additionally, AOC-13 FS, and AOC-4 PP and DD are underway and are partially complete.

While the contractor’s efforts in performing this work are ongoing, these tasks are not expected to be completed within the existing task order POP, and the Government requires completion of this work already being performed under the existing task order. The scope of the base contract W912DR18D0003 likely did not anticipate the POP of a task order would extend beyond five years and the ordering period of the base contract has concluded. The Government proposes to extend the POP of the task order to complete these tasks.

Justification:

The architect-engineer environmental services required to complete the tasks described above are considered to only be available from Leidos as defined in the authority of FAR 6.103-1 (DFARS CD 2026-O0017). This action represents a direct continuation of highly specialized, architect-engineer services already underway and is consistent with the progression of CERCLA cleanup actions. Leidos possesses unique experience with the specific hydrogeology and geology at the FNOD site, which is essential to successfully completing the tasks under this task order. Leidos’s highly specialized and unique knowledge of the site's environmental conditions, regulatory stakeholder expectations, and the specific methodologies required to complete the work for the Treatability Study, AOC-13 and AOC-4.

Pursuing a competitive solicitation to complete the requirement would result in substantial duplication of cost to the Government that is not expected to be recovered through competition or unacceptable delays in fulfilling the agency’s requirements. FAR 6.103-1(c)(2) (DFARS CD 2026-O0017).

Because Leidos has already authored the USACE-CX and EPA-approved Work Plan and conducted the baseline groundwater samplings, continuing this work under a new contract with a new contractor would duplicate the work and thereby provide significant delays, and be more costly to the Government. A new contractor would be required to review existing historical data, independently verify the baseline sampling results, and draft a new Project Management Plan, draft a Work Plan and associated Accident Prevention Plan (APP) and Quality Assurance Project Plan (QAPP) to align with their own corporate standard operating procedures. This duplication of effort would result in unnecessary expenditures of Government time and funds that yield no additional benefit to the project.

Leidos has also already started the AOC-4 PP and DD and AOC-13 FS, and its specialized services would take significantly more time for another contractor to complete. The reporting requires specialized services there would be a level of effort that would be duplicated; and more costly if another contractor had to come in and attempt to finish the documentation.

Cost It is estimated that competitive solicitation would result in of duplicative, unrecoverable costs. This estimate is based on the labor required to reprocure the services, and the contractor’s fees to redo/duplicate the tasks that will be required should a new contractor take on this work:

duplication of cost to the Government that is not expected to be recovered through competition or unacceptable delays in fulfilling the agency’s requirements.

Impact:

As explained above, if a competitive solicitation was issued, the Treatability Study and Documentation would be significantly delayed. Time would be lost navigating the procurement process, selecting, and onboarding a new contractor. More significantly, it is estimated that a new contractor would require several months to review all requirements, familiarize themselves with the site data, and draft new technical reports and work plans for approval by the Government, the EPA, and other stakeholders.

These schedule delays would cascade, impacting the overall FNOD remediation schedule and delaying the ultimate Record of Decision (ROD) and final remedy implementation. Furthermore, a competitive solicitation would require a substantial and duplicative financial investment by the Government to pay a new contractor to recreate planning documents and baselines that Leidos has already successfully established and gotten approved.

For these reasons, pursuing a competitive solicitation to complete the requirement would result in substantial duplication of cost to the Government that is not expected to be recovered through competition or unacceptable delays in fulfilling the agency’s requirements. FAR 6.103-1(c)(2)

(DFARS CD 2026-O0017).

6. Market Research and Efforts to obtain Competition:

As explained above, the Government contemplated the possibility of recompeting the service for completion of the requirement. A notice of intent was posted to SAM.gov in accordance with FAR 5.201 (DFARS CD 2026-O0003) on 20 July 2026 with responses due by 3 August 2026. It stated that any firm that believes they can meet this requirement should submit a capability statement that would be independently reviewed by the Government. The Government received no responses.

Original (2021) Procurement On February 17, 2021, the Contracting Office issued a Task Order Requirement Notice (TORN) to seven Indefinite Delivery/Indefinite Quantity (IDIQ) contract holders for Architect-Engineer (A/E) services in support of this HTRW project. The TORN provided the IDIQ contract holders an opportunity to submit supplemental information in support of their Standard Form (SF) 330 submissions. The Government’s selection of the contractor was based on the supplemental information submitted in response to the TORN, the SF 330 information on file, and the contractor’s past performance information available to the Government at the time of selection.
